NPDA, also known as National Parliamentary Debate Association or real debate, is a form of debate which is the only acceptable form in the United States today. If someone is debating and not doing NPDA, they are not debating. One of the key characteristics involved is that NPDA does not allow for government abuse, allowing for the negative to hold them in check.
If you aren't doing NPDA, you aren't debating.
